Questions about AMBA

What people ask.

Why is AMBA on Broken Stocks?

AMBA qualifies for the Watch on decline depth. It is down -25.1% from its rolling 252-day high of $96.69, set on 2025-11-12 — 281d ago.

Is AMBA a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. AMBA is down -25.1% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.

Is AMBA a buy?

Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.

Where is AMBA trading inside its 52-week range?

At $72.53, AMBA sits 50.1% of the way from its 52-week low ($48.30) to its 52-week high ($96.69). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has AMBA been declining?

The current 25.1% decline accrued over 281d, which annualizes to roughly -32.6% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.

How does AMBA compare to its sector?

There are 239 other Technology tickers on Broken Stocks: 148 Red, 50 Amber, 41 Watch, with 65 showing recovering structural signals. Median sector decline is -36.8% — AMBA's decline is shallower than the sector median.

Does AMBA's earnings date affect its tier?

No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-09-03) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
